Samba now features a pluggable passdb interface, along the same lines as the
one in use in the auth subsystem. In this case, only one backend may be active
at a time by the 'normal' interface, and only one backend per passdb_context is
permitted outside that.
This pluggable interface is designed to allow any number of passdb backends to
be compiled in, with the selection at runtime. The 'passdb backend' paramater
has been created (and documented!) to support this.
As such, configure has been modfied to allow (for example) --with-ldap and the
old smbpasswd to be selected at the same time.
This patch also introduces two new backends: smbpasswd_nua and tdbsam_nua.
These two backends accept 'non unix accounts', where the user does *not* exist
in /etc/passwd. These accounts' don't have UIDs in the unix sense, but to
avoid conflicts in the algroitmic mapping of RIDs, they use the values
specified in the 'non unix account range' paramter - in the same way as the
winbind ranges are specifed.
While I was at it, I cleaned up some of the code in pdb_tdb (code copied
directly from smbpasswd and not really considered properly). Most of this was
to do with % macro expansion on stored data. It isn't easy to get the macros
into the tdb, and the first password change will 'expand' them. tdbsam needs
to use a similar system to pdb_ldap in this regard.
This patch only makes minor adjustments to pdb_nisplus and pdb_ldap, becouse I
don't have the test facilities for these. I plan to incoroprate at least
pdb_ldap into this scheme after consultation with Jerry.
Each (converted) passdb module now no longer has any 'static' variables, and
only exports 1 init function outside its .c file.
The non-unix-account support in this patch has been proven! It is now possible
to join a win2k machine to a Samba PDC without an account in /etc/passwd!
Other changes:
Minor interface adjustments:
pdb_delete_sam_account() now takes a SAM_ACCOUNT, not a char*.
pdb_update_sam_account() no longer takes the 'override' argument that was being
ignored so often (every other passdb backend). Extra checks have been added in
some places.
Minor code changes:
smbpasswd no longer attempts to initialise the passdb at startup, this is
now done on first use.
pdbedit has lost some of its 'machine account' logic, as this behaviour is now
controlled by the passdb subsystem directly.
The samr subsystem no longer calls 'local password change', but does the pdb
interactions directly. This allow the ACB_ flags specifed to be transferred
direct to the backend, without interference.
Doco:
I've updated the doco to reflect some of the changes, and removed some paramters
no longer applicable to HEAD.

This time its the pdb_getsampwuid() function - which was only being used by the
SAMR rpc subsystem to gain a 'user session key'. This 'user session key' is
actually generated at login time, and the other changes here simply move that
data around.
This also means that (when I check some details) we will be able to use the
user session key, even when we are not actually the DC, becouse its one of the
components of the info3 struct returned on logon.

smbd, and also makes it much cleaner inside winbindd.
It is mostly my code, with a few changes and testing performed by Alexander
Bokovoy <a.bokovoy@sam-solutions.net>. ab has tested it in security=domain and
security=ads, but more testing is always appricatiated.
The idea is that we no longer cart around a 'domain\user' string, we keep them
seperate until the last moment - when we push that string into a pwent on onto
the socket.
This removes the need to be constantly parsing that string - the domain prefix
is almost always already provided, (only a couple of functions actually changed
arguments in all this).
Some consequential changes to the RPC client code, to stop it concatonating the
two strings (it now passes them both back as params).
I havn't changed the cache code, however the usernames will no longer have a
double domain prefix in the key string. The actual structures are unchanged
- but the meaning of 'username' in the 'rid' will have changed. (The cache is
invalidated at startup, so on-disk formats are not an issue here).

Samba (ab)uses the returns from getpwnam() a lot - in particular it keeps
them around for a long time - often past the next call...
This adds a getpwnam_alloc and a getpwuid_alloc to the collection.
These function as expected, returning a malloced structure that can be
free()ed with passwd_free(&passwd).
This patch also cuts down on the number of calls to getpwnam - mostly by
taking advantage of the fact that the passdb interface is already
case-insensiteve.
With this patch most of the recursive cases have been removed (that I know
of) and the problems are reduced further by not using the sys_ interface
in the new code. This means that pointers to the cache won't be affected.
(This is a tempoary HACK, I intend to kill the password cache entirly).
The only change I'm a little worried about is the change to
rpc_server/srv_samr_nt.c for private groups. In this case we are getting
groups from the new group mapping DB. Do we still need to check for private
groups? I've toned down the check to a case sensitve match with the new code,
but we might be able to kill it entirly.
I've also added a make_modifyable_passwd() function, that copies a passwd
struct into the form that the old sys_getpw* code provided. As far as I can
tell this is only actually used in the pass_check.c crazies, where I moved
the final 'special case' for shadow passwords (out of _Get_Pwnam()).
The matching case for getpwent() is dealt with already, in lib/util_getent.c
Also included in here is a small change to register the [homes] share at vuid
creation rather than just in one varient of the session setup. (This picks
up the SPNEGO cases). The home directory is now stored on the vuid, and I
am hoping this might provide a saner way to do %H substitions.
TODO: Kill off remaining Get_Pwnam_Modify calls (they are not needed), change
the remaining sys_getpwnam() callers to use getpwnam_alloc() and move
Get_Pwnam to return an allocated struct.

Thou shalt not reference SAM_ACCOUNT members directly - always use
pdb_get/pdb_set.
This is achived by making the whole of SAM_ACCOUNT have a .private member,
where the real members live. This caught a pile of examples, and these have
beeen fixed.
The pdb_get..() functions are 'const' (have been for some time) and this
required a few small changes to constify other functions.
I've also added some debugs to the pdb get and set, they can be removed if
requested.
I've rewritten the copy_id2x_to_sam_pass() functions to use the new passdb
interface, but I need the flags info to do it properly.
The pdb_free_sam() funciton now blanks out the LM and NT hashes, and as such
I have removed many extra 'samr_clear_sam_passwd(smbpass)' calls as a result.
Finally, any and all testing is always appriciated - but the basics seem to
work.

member server. Firstly, use the same max enumeration size (0x400) as W2K
uses, otherwise W2K won't ask for any more. Secondly, if a enumeration
request with a non-zero offset comes in on a handle that hasn't started
an enumeration, don't bitch about it (return NT_STATUS_UNSUCCESSFUL),
just load the db on that handle and return at that offset.

calculate them and always reply a size of 32 bytes whereas NT4 did the
maths. Anyway, it looks like the clients don't complain.
in query_dom_info() at level 2, return the real number of users and
groups. That's the fix to the W95/98 userlist bug !
as W95/98 does a query_dom_info(2) followed by a query_disp_info(4) on
the SAME context handle (err we call it an lsa policy handle ! plain
wrong name), I was tempted to keep the snapshoot in memory, to prevent
2 full user db enumerations in a row and just have one shared. But if some
client does the 2 calls on two different handles, we would have 2 copies
in memory not free'ed before the samr_close().
We still have too many fixed constant and too many magic values in that
code. And btw, I really hates how the sequence number is generated !

instead of enumerating the whole user db or group db every time, we store
a in memory copy linked to the handle.
that's much faster for large enumeration where the db can't fit in a
single rpc packet. And as it's a copy, it's constant between enumeration.
still some stuff to clean. But now I can fix the W95 userlist bug, as I've
finally found it.

It's just to keep usermanager happy ;-)
clean up a bit samr_query_aliasinfo to return the group description
added: samr_del_aliasmem, samr_del_groupmem and samr_del_domuser
with the correct scripts, you can now entirely manage the users from
usermanager ! Closer to full PDC every day ;-)

- removed the ugly as hell sam_logon_in_ssb variable, I changed a bit the
definition of standard_sub_basic() to cope with that.
- removed the smb.conf: 'domain admin group' and 'domain guest group'
parameters ! We're not playing anymore with the user's group RIDs !
- in get_domain_user_groups(), if the user's gid is a group, put it first
in the group RID list.
I just have to write an HOWTO now ;-)

not the privileges. Usually we don't need them, so the memory is free
early.
lib/util_sid.c: added some helper functions to check an SID.
passdb/passdb.c: renamed local_lookup_rid() to local_lookup_sid() and pass
an RID all the way. If the group doesn't exist on the domain SID,
don't return a faked one as it can collide with a builtin one. Some rpc
structures have been badly designed, they return only rids and force the
client to do subsequent lsa_lookup_sid() on the domain sid and the builtin
sid !
rpc_server/srv_util.c: wrote a new version of get_domain_user_groups().
Only the samr code uses it atm. It uses the group mapping code instead of
a bloody hard coded crap. The netlogon code will use it too, but I have to
do some test first.

You can change them with either usermanager->policies->account
or from a command prompt on NT/W2K: net accounts /domain
we can add a rpc accounts to the net command. As the net_rpc.c is still
empty, I did not start. How should I add command to it ? Should I take the
rpcclient/cmd_xxx functions and call them from there ?

This time it's a PRIVILEGE_SET struct instead of a simple uint32 array. It
makes much more sense. Also added a uint32 systemaccount to the GROUP_MAP
struct as some privilege showing in USRMGR.EXE are not real privs but a
bitmask flag. I guess it's an heritage from NT 3.0 ! I could setup an NT
3.1 box to verify, but I'm too lazy (yes I still have my CDs).
Added 3 more LSA calls: SetSystemAccount, AddPrivileges and
RemovePrivileges, we can manage all this privilege from UserManager.
Time to change the NT_USER_TOKEN struct and add checks in all the rpc
functions. Fun, fun, fun.

We now get the full account policy window in usermanager, and the
framework to store all those values. I plan to add a TDB file to store
them.
oh, and found that the last value in a sam_unknown_info_12_inf struct is
an uint16 and not a uint32.
andrewb: you hardcoded the MAX_PASSWORD_AGE to 21 days. We can now turn it
to a value setable in usermanager.

an array of uint32. That's not perfect but that's better.
Added more privileges too.
Changed the local_lookup_rid/name functions in passdb.c to check if the
group is mapped. Makes the LSA rpc calls return correct groups
Corrected the return code in the LSA server code enum_sids.
Only enumerate well known aliases if they are mapped to real unix groups.
Won't confuse user seeing groups not available.
Added a short/long view to smbgroupedit.

In particular this commit focuses on:
Changing the Get_Pwnam code so that it can work in a const-enforced
environment.
While these changes have been mildly tested, and are pretty small, any
assistance in this is appreciated.
----
These changes allow for 'const' in the Samba tree.
There are a number of good reasons to do this:
- I want to allow the SAM_ACCOUNT structure to move from wasteful
pstrings and fstrings to allocated strings. We can't do that if
people are modifying these outputs, as they may well make
assumptions about getting pstrings and fstrings
- I want --with-pam_smbpass to compile with a slightly sane
volume of warnings, currently its pretty bad, even in 2.2
where is compiles at all.
- Tridge assures me that he no longer opposes 'const religion'
based on the ability to #define const the problem away.
- Changed Get_Pwnam(x,y) into two variants (so that the const
parameter can work correctly): - Get_Pwnam(const x) and
Get_Pwnam_Modify(x).
- Reworked smbd/chgpasswd.c to work with these mods, passing
around a 'struct passwd' rather than the modified username

The big one is a global change to allow us to NULLify the free'ed pointer to a
former passdb object. This was done to allow idra's SAFE_FREE() macro to do
its magic, and to satisfy the input test in pdb_init_sam() for a NULL pointer
to start with.
This NULL pointer test was what was breaking the adding of accounts up until
now, and this code has been reworked to avoid duplicating work - I hope this
will avoid a similar mess-up in future.
Finally, I fixed a few nasty bugs where the pdb_ fuctions's return codes were
being ignored. Some of these functions malloc() and are permitted to fail.
Also, this caught a nasty bug where pdb_set_lanman_password(sam, NULL) acheived
precisely didilly-squat, just returning False. Now that we check the returns
this bug was spotted. This could allow different LM and NT passwords.
- the pdbedit code needs to start checking these too, but I havn't had a
chance to fix it.
I have also fixed up where some of the password changing code was using the
pdb_set functions to store *internal* data. I assume this is from a previous
lot of mass conversion work...
Most likally (and going on past experience) I have missed somthing, probably in
the LanMan password change code which I havn't yet been able to test, but this
lot is in much better shape than it was before.
If all this is too much to swallow (particularly for 2.2.2) then just adding a
sam_pass = NULL to the particular line of passdb.c should do the trick for the
ovbious bug.

- call pdb_reset_sam() after each getent call.
Fix bug in get_group_alias_entries(), were if num_entries was zero this caused
talloc() to return NULL, failing a test below with NT_STATUS_NO_MEMORY.
Fix pdb_reset_sam() to correctly initalise the sam structure.
Move default value code into a single place, likewise for sam freeing code.
- should make things easier if we decide to malloc other strings, or get more
non-zero default values.
Finally, add a function in init a sam struct from a getpwnam() return.
